Cannot read Razor IMU

['Aliah]

Hi, I'm using this https://decibel.ni.com/content/docs/DOC-14911 example to read my Razor IMU. However, my labview can't detect the COMport. Am I missing something?

Also, I tried on another computer, and it was able to read, however, the data wouldn't appear on the graph. Please advice. 

Thank you 🙂

Sorry. I just realized. It's because I have not downloaded the necessary driver. 

I still can't get the data to appear on the graph though.

Is it because the string data from the IMU is not being converted? Help! I've been stuck on this for 2 days now.

You've got an indicator on the front panel of TestVISerialIMU that shows the data from the device. What do you have in that indicator? When you probe the error wire from the VISA Read or from the ConvertString subVI, what do you see?

Hi Dennis 🙂

They all show "0", however the IMU text does display data. And when probe error wire from the VISA Read, ït says {status => False; code => 0; source => ''}

Is there something wrong with the ConvertString_RollPitchYaw?

[Dennis_Knutson]

Why don't you actually post the VI AND that shows the data? This is simple to do. Run the VI until you have data showing in the string indicator. Go to Edit> Make Current Values Default. Save the VI. Attach it. Then someone can see if the parser is not working or you are getting incorrect readings.

Here it is

As you can see in the subVI ConvertString_RollPitchYaw (SubVI), the expected start of the string is !ANG:. The start of the string you are getting is #YPR=. Change the subVI to get ypr values. I have no idea if there is something wrong with you getting a different prefix.

I changed the subVI and it worked! Thank you so much, Dennis.
